    摘要： A projection system including light emitting units, a scrolling unit, and a light valve. The light emitting units emitting light beams of different wavelengths. The scrolling unit has spirally arranged cylinder lens cells which separate the light beams into color beams and scroll the color beams when the scrolling unit is rotated. The light valve receives, at different positions, the color beams transmitted by the scrolling unit and forms a color image by turning pixels on or off according to an input image signal.

    摘要： A projection system including a light source, a color separator, a scrolling unit, a light valve, a wire grid polarization beam splitter, and a projection lens unit is provided. The color separator separates an incident beam according to color. The scrolling unit scrolls the color beams. The light valve processes an incident beam according to an image signal and forms a color picture. The wire grid polarization beam splitter is disposed between the scrolling unit and the light valve and transmits or reflects an incident beam according to a polarization of the incident beam. The projection lens unit magnifies the color picture formed by the light valve and reflected by the wire grid beam splitter and projects the magnified color picture onto a screen.

    摘要： A spiral lens disk and a projection system adopting the same are provided. The spiral lens disk has spirally arranged cylinder lens cells and scrolls incident light by converting the rotation of the cylinder lens cells into rectilinear motion of a cylinder lens array. The projection system includes at least one spiral lens disk such that color scrolling is achieved using a single component to form a color image. Due to a reduction in the number of components, a light, low-price projection system can be obtained, and a single-panel projection system with high light efficiency can also be obtained.

    摘要： A projection system that can adjust color balance of incident light is provided. The projection system includes a light source, a spatial filter, an optical separator, a scrolling unit, a light valve, and a projecting lens unit. The spatial filter has a slit to adjust a divergent angle or etendue of light emitted from the light source. The optical separator separates light passing through the spatial filter according to color of incident light. The scrolling unit has one or more spiral lens discs, which are formed by spirally arranging cylindrical lens cells, rotate, and scroll color beams separated by the optical separator. The light valve processes light passing through the scrolling unit according to an image signal and forms an image. The projecting lens unit magnifies the image formed on the light valve and projects the magnified image onto a screen.
